Application filed April '21, 1920. Serial No. 375,521.

To allwham itma concern:

Be it known t at I, ERWIN L. Wanna, a citizen of the United, States, and residing at Seattle, in the county of King and State of Washington, have invented certain new and useful Improvements in "Heating Devices, of which the following is a specificae invention is illustrated in the accom- .panying drawings, in which F igure 1 is a perspective view illustrating the application of the improvement to a room.

Fig. 2 is a section through the window frame of Fig. 1.

In carrying out the invention base boards 1 of the room structure, and also the frames 2 of the windows, but one such frame bein shown, are of hollow construction, and pre erably of thin' sheet metal.

The heater, here shown as a hot air furnace 3 is provided with a main hot air pipe 4 which, directl and through'branches 5 leads to the baseboards 1 and to thewindow frames 2. Return pipes 6 lead from the base boards and window frames to the main return 7 to the furnace. A pump or blower 8 may be arranged in the return-pipe 7 in order to insure the desired activity of the circulation. l

It. is of course to be understood that the various pipes to and from the main feed and return pipe of the furnace are to be so arranged that a proper and desirable circulation of the heating medium may be had in order that the material of the base boards and window frames will become heated, and thereby radiate the heat into the room. Suitable valves 9 or dampers may be provided whereby the circulation of the heating medium may be controlled at will.

It is further contemplated that any type of circulating heatin medium may be used, the conventional air urnace here illustrated being therefore indicative of all such types.

What I claim is: The combination with a hollow base board of a room and a hollow window frame for pipe leadsaid room of a heater, a heating ing therefrom, branch heating pi es leading from said pipe into the hol ow base board, return pipes leading from the base board 'to'the heater, a branch pipe leading from one of the branch heating pipes-to the hollow window frame, a return pipe leading from the hollow window frame to one of the return pipes from the base board to the heater, and means arranged in the re- ,turn pipe leading into the heater to compel a circulation of the heating medium.

In testimony whereof I affix in Si nature. ERWIN L. E ER.
